USP-Gaussian: Unifying Spike-based Image Reconstruction, Pose Correction and Gaussian Splatting

1 code implementation15 Nov 2024 Kang Chen, Jiyuan Zhang, Zecheng Hao, Yajing Zheng, Tiejun Huang, Zhaofei Yu

Leveraging the multi-view consistency afforded by 3DGS and the motion capture capability of the spike camera, our framework enables a joint iterative optimization that seamlessly integrates information between the spike-to-image network and 3DGS.
